The horse has a limited range of hip movement compared to a dog. This is mainly restricted to flexion and extension and is a result of the conformation of its femoral head, intraarticular ligaments and a large muscle mass around the joint. Unlike other species the horse also has an extra ligament present in the joint; the '''accessory ligament'''. | The horse has a limited range of hip movement compared to a dog.
